The Role of Competition and Predation in Ecology - Competition and predation are two key factors that affect the stability of an ecosystem, such as a lake. There are three theories on the affects of competition. Competition may lead to competitive exclusion, stable coexistence, or niche differentiation. It has been shown that in marine environments, species are strong competitors for both light and nutrients and thus competition leads only to competitive exclusion (Passarge et al. 2006). The competitive exclusion principle states that if two species compete for the same resource in the same location, then one of those species will go extinct because one species will be the better competitor (Jenson 2010)....   [tags: ecology]

Indigenous Knowledge and Ecology - The mistake of culture as timeless, knowledge as data Take a walk down Bourke’s main street and about midway, on the northern side, you will see a panoramic mural spanning the roofline of a simple brick building. It is a kind of timeline. At one end there is a panel devoted to Aboriginal life and Dreaming before colonisation, while the rest of the panels show a sequence of white exploration, pioneer settlement, a changing pastoral industry, reminders of historic floods, and a modern outback town....   [tags: Ecology] 914 words

The Impact of Sea Otters on Marine Ecology - Sea otters (Enhydra lutris) are marine mammals capable of spending their entire lives in water. Being carnivorous in nature, they feed on sea urchins, crabs, fishes, mussels and clams. They are referred to as keystone species due to their profound impact on marine ecology. The interaction between sea otters, sea urchins and kelp forests has been studied as a model of the impact of predator-prey interaction on community ecology. Sea otters are keystone predators, whose presence has a far-reaching influence on the marine food web by affecting the population of sea urchins in particular, and kelp forests & other marine organisms in general....   [tags: Ecology ]

Theories of Social Ecology - All three theories by Heidegger, Bookchin, and Naess are based on the normative assumption: humans perceived themselves as being distinct from a world that unites both humans and non-humans. To better understand the distinguishments that each author makes in his theory, I will reconstruct each of their assumption. After that, we will explore the rational fashioning of integrative ways and the problems that it raises. In conclusion, there may be a reiteration of the assumption in our effort to act ethically according to the ecosystem....   [tags: Social Ecology]

The Influence of Species Ecology on the Performance and the Generality of Species Distribution Models - The ongoing alteration of ecosystems through human activity (IPCC 2007) endangers vitally important resources and leads to the rapid extinction of species world wide. Research is needed to assess the ecological impacts and consequences of this change, but for large parts of the world detailed species inventories are difficult – if not impossible – to obtain. Attempts to protect individual organisms (Gibson et al. 2004) or whole ecosystems (Williams et al. 2003) therefore increasingly depend on ecological modeling techniques....   [tags: Ecology ]

Social Ecology versus Differential Association - Social Ecology versus Differential Association Which is a better theory of crime Social ecology or differential association.

Overview of Ecology Topics: Energy Flux, Food Webs and Resources - ... This is termed intraspecific competition. These effects can be extended to include pairwise interactions between species (e.g. competition, mutualism, predator-prey), which is termed interspecific competition. To illustrate this concept and how it relates to resource limitations, the concept of predator-prey interactions will be discussed briefly. Gause conducted early experiments on simple species such as yeast and paramecia to examine simple species assemblages and determine theoretical conditions of resource abundance that might allow species to stably coexist (Gause 1934)....   [tags: Communities, Systems] 1399 words

The Evolutionary Importance of Maternal Anti-Bodies and its Implications on Evolution and Ecology - An organism’s ability to survive is not limited to the number of resources available but even more importantly the organism’s ability to fight off infections. Immunity is one of the most important features an organism has to distinguish and protect itself against certain pathogens that could potentially be fatal to the organism. From the first line of defense such as skin and mucous membranes, an organism’s body is constantly fighting off antigens. Antigens are molecules from a pathogen or a foreign organism that provoke a specific immune response....   [tags: Research Analysis ]

Viruses are very small at generally 20-200nm, and have a simple structure consisting of genetic material with a protein coat, and sometimes a lipid envelope(2). Due to their simplicity, viruses rely on exploiting living cells and using the host’s cellular machinery to replicate(3). Irrespective of their size, viruses have been found to have a significant influence on many ecological processes and biogeochemical cycles in marine ecosystems(2, 4)....   [tags: ocean ecology]

Amphibians - Amphibian means “double life” referring to the fact that most adult amphibians live on land while embryos need water to survive.

There is no single cause of the amphibian decline, but it seems that habitat loss, like deforestation, is the main reason along with human impact in terms of urbanization, forest fragmentation, predation, human exploitation, pathogens and climate change (Hayes, Falso, Gallipeau, Stice 2010)....   [tags: Ecology ]
